7.2 Calibrate the Scanner
Calibrate only if the scanned image looks fuzzy, the color looks abnormal (e.g., darker than
normal), after more than 8,000 scans, or the scanner has been stored without use for a long
time. The calibration process resets the Contact Image Sensor to resume its color and
sharpness precision.
1. Open the document extension plate.
2. Make sure the Document Guides are unfolded as shown in the image (1).
3. Hold the edges of the calibration sheet (which you find in the product box) and insert it
with the text FACING DOWN (2).
4. Align it to the right and make sure the white area is fed first (3).
5. Turn on the scanner by moving the Power switch to the [ON] position.
6. To enter the calibration mode, press and hold the [Color/BW] until [CAL] is displayed
on the screen and the [Scan] LED flashes in green , indicating you are in calibration
mode.
7. Press the [Scan] button. The calibration sheet will be fed through.
8. When the calibration process is finished, [OK] is displayed on the screen.
